Well, that didn't last long. Mere days after Nine Inch Nails unveiled their first new track in a jillion years, the brilliant Came Back Haunted from their forthcoming album Hesitation Marks, guitarist Adrian Belew has announced that he's left the band.

Belew's initial announcement of the parting of ways was a Facebook message which read: "Hey folks … I greatly respect Trent and the music he makes. No one is at fault. We both agreed it just was not working … NIN will do an amazing show and I am back where I belong: creating [solo album] Flux."

Belew later deleted that message and replaced it with a much more succinct one: "Concerning me being part of the 2013 Nine Inch Nails band: it didn't work."
